I bought a can from G & G Hobby here in Houston. $37 plus tax.
WITHOUT QUESTION THE ABSOLUTE BEST CHROME ON THE MARKET.
I do a lot of aircraft and you are always looking for realistic metal finish. This is hands down the best. After spraying it and letting it sit for 24 hours, I've masked over it with masking tape and had no issues with lifting or peeling. I agree it is expensive, but I've tried pretty much everything out there and this is hands down the best you can get if you want a plated metal finish.
